But then presumably the designer of your camera isn't claiming to be an omniscient, omnipotent creator of the universe who demands worship
No - the designer is just an intelligent human (or group of humans) who design and construct cameras. If not for these humans digital cameras would not exist -or would they have evolved to? Intelligence existed first before the camera (that's kinda my point).
Also, your camera engineer presumably hasn't left in fundamental design flaws he has fixed in other cameras he has designed.
Who decides if something is a flaw or not. People point to other living things that clearly have better eyesight than humans as proof "somehow" that God bungled human eye sight. To live my life I do not need eagle eye vision or radar sight or night vision - my eyes are just fine for me.
And yes. eyes are not perfect - no part of a human being is perfect. I am sure I read that in a book somewhere..............
